Relating to agreements between sheriffs and the United States Immigration and Customs Enforcement to enforce federal immigration law.

HB 5580 requires sheriffs in Texas counties with 100,000+ residents to seek written agreements with U.S. Immigration and Customs Enforcement (ICE) under federal Section 287(g), allowing local officers to enforce federal immigration law. Sheriffs in smaller counties may also pursue such agreements. The bill mandates that agreements specify scope, duration, and limitations, and requires sheriffs to allocate necessary resources for implementation. It also creates a competitive grant program to fund sheriffs in counties under 1 million population that have entered these agreements, supporting their participation through detailed implementation plans. The legislation directly affects county sheriffs and their departments across Texas.
